Ductwork & Fabrication

We manufacture ductwork and accessories at our workshop in Al Sina’iyah — galvanised, black and stainless steel, to SMACNA, BSI and DW144. We fabricate for our own installations and supply other contractors. Sheet metal plant, insulation and stock are held on site, so a duct package does not depend on a third party’s queue.

When you need this

  • A duct package needed to a programme, where lead time drives the finish date
  • Fittings that do not exist off the shelf — transitions, breeches, odd angles
  • A kitchen extract that has to be stainless and has to fit the space it is in
  • Noise breaking out of a duct run into an occupied space
  • Sand and dust entering through intake louvers
  • Ductwork that has to be specified to a named standard for sign-off

What we provide

  • Galvanised, black and stainless steel ductwork (SMACNA, BSI, DW144)
  • Spiral ductwork and round fittings
  • Volume control dampers and splitter dampers
  • Air extractors and sound attenuators
  • Louvers and sand trap louvers
  • Acoustic liners for noise control
  • Custom stainless steel kitchen hoods
  • Mild steel fabrication — angle frames, channels and support stands
  • Pre-insulated rectangular and round duct
  • Aluminium cladding and air balancing
